Use and maintenance of the single-lens reflex camera
The usage of the DSLR: - [Exposing Mode: Understand exposure modes such as M and P.] The P-mode was automatic, and the camera would automatically set the shutter speed and aperture to obtain the best exposure. It was suitable for taking shots or when there was no time to adjust the camera settings. Although the exposure could not be changed, the exposure parameters could be selected independently. The M-mode was manual mode, and the user could completely control the shutter speed, aperture, sensitivity, etc. For example, setting the shutter speed to B-door or remotely controlling B-door could achieve a long exposure. - Different shooting scenes: When shooting portraits, use a large aperture (within F5.6) and a focal length of 50mm or above. The shooting distance is determined according to the full body, half body, and head shot to achieve background blurring. You can choose the audio file for shooting scenes, use an appropriate aperture (above F8), and the focal length can be freely selected. However, it may be easy to produce distortion when shooting with a wide angle. DSLR maintenance: - Cleaning: - After each use, clean the lens and the outside of the camera with a soft brush, especially around the interface and switch buttons. - Regular cleaning. It is recommended to thoroughly clean the DSLR camera every 3 - 6 months. Use a dust collector to remove dust from the lens and the interior of the camera (professional dust collectors are recommended). Gently wipe the inside and outside of the camera with a rubber brush (avoid touching the lens and sensors). Use professional cleaning solution to clean the lens and the exterior of the camera to remove fingerprints, oil stains, and dirt. - The cleaning of the camera should be comprehensive, and the corners should not be missed. As for the coating in front of the lens, because it is very thin (0.0001mm), it will be damaged if it is wiped often. You can add a UV-lens (anti-oil, dust-proof and easy to clean). When cleaning the lens, camera or sensor, you must use special cleaning tools. - Other maintenance: - Dust-proof: In dusty places, use your hands, lens cap, or soft cloth to block the lens; before departure, determine the commonly used lens and install it properly. If you need to change the lens, find a leeward place to quickly change it. Hold the lens barrel and rotate it without moving. - Shockproof: The camera and lens are fragile. When in use, avoid physical damage such as impact and falling. When not in use, put it in a camera bag with an air cushion. - Anti-humidity: In areas with high humidity or during the rainy season, you can buy a waterproof box (maintaining 40% - 50% humidity) to store the camera and accessories. If you don't have any conditions, you can buy a drying agent or color-changing silica gel to dry it. Try to avoid shooting in rain and snow. - Magnetic Field Protection: The camera should be kept away from electrical appliances with strong magnetic fields such as televisions, radio, refrigerator, and microwave to prevent the lens aperture blades from being magnetized and the memory card data from being lost. - High and low temperature protection: When shooting at low temperatures (such as-30 ° C), prepare more batteries to keep warm. In summer, avoid putting the camera in the trunk of the car to prevent the battery from bursting. - Water-proof and anti-glare: avoid shooting on rainy days. If you have to shoot on rainy days, you can bring a waterproof camera bag. When shooting, use an umbrella or plastic to protect the lens. Do not shoot directly under strong light for a long time to avoid burns on the sensor. - Batteries and memory cards: If you don't use the camera for a long time, clean and remove the batteries and memory cards before storing them, and place them in a dry and cool place. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Single lens reflex camera
If you wanted to turn a DSLR into a computer camera, there were two options. One was to use the transmission software introduced by the camera manufacturer, but this solution had shortcomings. For example, many software did not support it, could not recognize it, and the quality of the transmitted image was relatively low. The other method was to use an acquisition card. The function of the acquisition card was to transmit the image of the camera and other equipment to the computer in real time. The high-end acquisition card also had a built-in cooling fan, support loop out, audio input and output functions. However, when choosing a capture card, you need to pay attention to its ring resolution, capture resolution, and other parameters. For example, capture cards below 100 yuan usually only support 1080P (the actual effect may not be achieved), capture cards around 200 yuan support 4K ring, but the resolution collected on the computer may also be 1080P. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The lens mount of a Nikon single-lens reflex camera was an F-mount. From the early film DSLR to the recent digital DSLR, they all used F-mount. In terms of F-mount lenses, due to the different mechanical/electronic transmission methods of aperture adjustment, aperture information transmission, focal length information transmission, and autofocus, there were many types of single-lens reflex lenses. For example, manual non-CPU lenses included STAR lenses, AI lenses, AIS lenses, etc. According to the type of aperture adjustment, there were D-type lenses with manual aperture rings, G-type lenses without manual aperture rings, E-type lenses with electromagnetic apertures, etc. The F-mount lens was divided into two types: the FX-mount lens (suitable for all Nikon single-lens reflex cameras, similar to Canon's EF-mount lens) and the DX-mount lens (suitable for Nikon APS-C format cameras, similar to Canon's EF-mount lens). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Single-lens reflex camera with glasses
If you wore glasses and used a single-lens reflex camera to shoot, most single-lens reflex cameras had a refraction adjustment function. You can aim your eyes at the viewfinder, and after automatically focusing on an object, adjust the refraction adjustment button to the left or right until you see the clearest image. However, the position of the refraction adjustment button might be different for different brands of DSLR. It was usually next to the viewfinder. In addition, there were also photographers who said that they could see the viewfinder clearly with a single-lens reflex camera. If you feel that the image you see through the viewfinder is blurry, you can also consider putting on your glasses and shooting directly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The parameters of a single-lens reflex camera
The following are some important settings for a DSLR camera: 1. ** Shooting Mode **: It is recommended to choose the manual mode (M). This way, you can control the shutter, aperture, sensitivity, and other parameters independently. 2. ** Video recording format and size **: If there are no special requirements, you can choose to record 1920*1080, 25 frames, MOV format of high-definition video. If there are special requirements for zooming in, you can choose 4K or other format. 3. ** Shutter Speed **: Generally, it is twice the frame rate of the video. For example, when the frame rate is 25 frames, the shutter speed is set to 50; when the frame rate is 60 frames, the shutter speed is set to 120. This way, the visual effect can be achieved. 4. ** Aperture **: The aperture size affects the depth of field of the picture. A large aperture (such as F2.8) made the picture brighter and the background blur stronger, while a small aperture (such as F11) made the picture darker and the background blur weaker. The larger the aperture value, the smaller the actual aperture. 5. ** Light sensitivity (USB)**: When there is sufficient light, the lower the USB, the better. It is not advisable to set it too high in a dark environment, otherwise it will produce noise. For example, Canon DSLR can be set to 100 during the day and 800 - 1000 at night. A high USB (greater than 2000) will produce obvious noise and it will be difficult to repair later. 6. ** Color temperature (white balance)**: adjust to manual mode. Generally, it is recommended to adjust the color temperature between 4900 and 5300. The higher the color temperature, the more yellow the screen will be, and the lower the color temperature, the more blue the screen will be. 7. ** Focus **: If you have good manual operation ability, you can try to manually focus and select the focus point. Novice or for convenience, you can use the automatic intelligent autofocus. However, it is recommended to practice manual focus more if possible. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
